When I bought my car it came with a Flowmaster exhaust system and K&N intake. It's a base 1997 5 spd. I recently just bought a magnaflow hi flow cat because my current one is busted. Once I get that installed, I'm just curious how much hp am I lookin at? thanks in advance

 

If the old cat was blown out you probably have less power now than you had before. If the old catwas clogged you are getting a good power boost. Altogheter I venture around 20HPover stock.

 

alright thanks man....I'm getting the new cat installed tomorrow so I'll let you guys know how it goes

 

i will say 15 20 hp for sure

 

I got it installed today....and I must say it sounds awesome! Inside the car, it's not so noisy anymore and I can really hear it coming from the back better. I also noticed an increase in power as I shifted through the gears. Love it!

 

anyone know about the 85 2.8 liter fuel injected weight or hp (I'm look'n stock) * have tak'n out about 100lbs well how much diff is stock to z28 rims? I figure they're lighter* thahnks nick
